An eBook reader can be a software application for use on a computer such as Microsoft's free Reader application, or a book-sized computer that is used solely as a reading device such as Nuvomedia's Rocket eBook. Users can purchase an eBook on diskette or CD, but the most popular method of getting an eBook is to purchase a downloadable file of the eBook or other reading material from a Web site such as Barnes and Noble to be read from the user's computer or reading device.

Generally, an eBook can be downloaded in five minutes or less Browse by Genre Available eBooks Jamil S.

Spoofing vs. People seem to think that as long as the problem can remain invisible to them , nothing bad is happening. What actually happened back in the day before people started forcing the issue with full disclosure was that the bad guys operated with impunity because the good guys couldn't work together because people got upset when folks let the "secret" vulnerability knowledge out. I don't want to go back to those days.

Things have improved so much since then. Please reread the name of this site. I'm surprised that so many members of a site named "Hacker News" agree with you that what is clearly a very clever hack is inherently a bad thing. This "clever hack" is costing a lot of people a lot of money today. Concrete example: are you a location based startup? Multiply that by thousands and you'll begin to have some idea of the discussions going on at every web based company with a clue today.

For those who make their living in computer security, like Mr. Butler, of course it's a good day and month, and year. Pretty good business when you can start fires and then get paid well to put them out. Serves them right, of course, because they shouldn't have built that house out of wood in the first place. While we're on the topic, I don't understand how a lot of people fail to realize that spending on computer security is a lot like spending on national security -- you can always spend more money on it, thereby taking away resources from other priorities.

This world in arms is not spending money alone. It is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. This is not a way of life at all in any true sense. Under the clouds of war, it is humanity hanging on a cross of iron. Not necessarily a clever hack nothing new here , just a user-friendly interface.

You don't need to use https for everything -- you can specify a domain and a path in the cookie. For things like images, videos and css, you still don't need SSL. Many browsers give warnings when mixing secure and insecure content. Know of a good cross-browser example that mixes http and https requests? That's a good point -- I hadn't thought about this. It is nice to see a common security issue taken seriously, but for me the even worse gigantic hole is that most people use only one password for their email account and all other accounts.

This is kind of a big deal. Not a whole lot of people are aware of this vulnerability and among those who are it's likely only a small subset that knew how to exploit it until now. I suspect all of the coffee shops in the college town where I live will have people using this starting tomorrow. I've personally been working from cafes and tunneling everything through SSH for years, but in my experience almost no one else does this. That's why the net effect of this is going to be exactly what the author wants.

Sniffing Attacks

All major potential targets will update this really fast. I can't think of a more effective way for him to convince them all to update now. I've personally been working from cafes and tunneling everything through SSH for years To where? I suspect it's to a server, VPS, or similar, and the connection is unencrypted from there to its endpoint. This being the case, could someone with a server on the same subnet be running a browser remotely or even just tcpdump and doing a similar thing with your logins?

This is just some thinking out loud and I may be totally wrong - correct me ;-. Virtually no modern wired networks use hubs anymore, they're for the most part switched.

Unlike wireless networks where packets are broadcast freely in to the air, the switch checks the destination address and sends the packets only to the endpoint. There are some attacks like arp-spoofing and flooding which can defeat this, but they don't work well against modern enterprise-grade switches like you would find in a data center. Have a bazillion karma points. I didn't realize that switching resolved that whole problem. This is why I continue to bring up stupid hypothetical situations on HN from time to time ;-. Switching doesn't resolve the problem completely.

There are a range of complicated attacks that could be done, but can be detected in various ways in a well run NOC. But we're talking a lot more complicated and deliberate than running tcpdump or this Firefox plugin, right? So I'd agree, more complex definitely, significantly not as much perhaps it depends on the type of attack as tool , as for deliberation I'd say about the same as the firefox plugin.

If you do run tcpdump you do pick up broadcasts and such, one of our VPS instances actually sees a load of DNS traffic for our subnet, which we think is the other VPS instances. It depends on how secure the remote network is. If it's just another coffee shop, you're screwed. If it's your own Linode in one of those well managed datacenters, it would be pretty difficult for anyone to snoop that traffic. If you control the remote network, it's a lot safer than having all your traffic unencrypted on the Starbucks Wifi.

What is Firesheep?

This is one of many reasons Loopt has used SSL for all[1] traffic from the very beginning. At least WiFi has fairly limited range. Cell networks[2] and satellite internet[3] can be sniffed miles away. In addition to making session hijacking harder, using SSL keeps crappy proxies from caching private data.

Dedicated to methods of exploiting systems and how to mitigate attack!

The cause was a mis-configured caching proxy. Raising awareness of issues like this gets them fixed. Until a service's users demand SSL, it won't be offered. Unless the service is Loopt : It's not a noticeable computational burden, but it does increase latency and cost money for certs. Not images 2. Older GSM crypto can be hacked in real time with rainbow tables now 3.

Usually not encrypted at all. Indeed, Loopt appears to be one of the few high-profile sites to have done this right.

SSL for everything, and cookies that are relevant to login sessions are marked secure. This is what we need everywhere! Some routers can be configured to drop clients more than N meters away, though.

Session Hijacking | Maximum Mac OS X Security

Groxx on Oct 25, A solid demonstration to show next time your webmaster doesn't want to set up SSL everywhere. That said, the current cartel-like setup of certificate authorities protection money and everything! Especially for small-scale projects. But there's really no excuse for larger sites. No more having multiple websites on one IP address. There's TLS 1. That's an incredibly drastic change and I seriously doubt it can even be done with IP4. SSL is bad for the environment because it requires far more server side hardware Well, I'm only partially serious about the environment thing, the question is, how can internet companies make it commercially viable to use SSL for everything?

The added hardware and power costs make each user way more expensive, possibly to the point where they may not actually be worth it.

What cost-effective solution would you suggest? EricButler on Oct 25, Regarding IPs, there's a bigger issue here. People are used to being able to shut their laptop at home and open it back up at work without having to re-authenticate all their browser tabs. If you filter by IP this breaks. SSL requires no changes to user behavior.

What about pairing the auth token with a browser fingerprint? People bring up the Google stat, but you have to remember they have incredible engineering resources so they probably optimize in many features every day without adding additional machines. That doesn't mean every dude with a LAMP stack out there can turn on SSL and expect the same performance, just that it's possible with mongo manpower and talent to make it work.

Google doesn't even release the details of their web stack so comparing their stat is apples and oranges.
